To all whmn 2'15 may concern Be it known that I, Enwm R. 011.1,, a eitizen of the United States, residing in the city of Y onkers, county of \Vestehester, and State of New York, have invented e certain. new and useful Improvement in Sup; ;orts i'er iocandescent- Lamps, of which the Fniiowing is a s eeificetion.

'l his invention has reletien to an im noved form of support for lairqssoei sis, wi erehy incandescent eieccric lei-ops he iuli idlf; and easily instelied by the use ef means previding a maxinnlm of safeig hem fire or leek age. The means employed are siinpie, cheap, and easily molded from parse sin or any ether ap ropriste material.

y invention is illustrated in :1 preferred form in the accompanying i'lmwings, "wi'iere Flgure 1 is a vertical section of my device as applied to e ceiling. Figs. 2 end 3 pies Views-0f the two arts of my devise run; .i through one'hum red and eighty degrees as com ered with Fig. i and shearing t whic come together. Fig. 4 e 1 derneath the device, end Fig 5 is s {in sii f s. contact-spring used in my seeket.

This device is composed sf "what 3:

two arts or sections being easily sereirenie.

The amp is carried on one section, which. is

carried by the other, this letter i attached to the well or eeiiingr and, seii as the su port for the whole. Ir is one sieves tage ofthis invention that it pro rides a sheep and easily-handled means whereby his ei' the wires which supnly the urr si in the lamps are supported independentiy of the lam supporting member 01'' the sashes and at t e same time ere eliestnsiig ere. rved fromcontaetwithwellser ceilings wi d mg danger from lire end less ei' cur mt by leakage. In the preferred form shewe the well-section 1 is supported si e. emisiderebie distance above the well or ceiling by mamas of rounded feet 2, joined by an J'UHil, ene-heii of which is seen at 3 in Fig. l.

rovirled with pelforehiuns 4, ilirinrgh which holts 01' screws can he passed, as indies-Lied in the dotted lines in Fig. 1. The main body of the welPsection extends at right; angles is the line joining the (renters of the t'we feet '5, and is rovided with two pairs ni' cavities in two di erent planes. The inner cavities are shown at 5 and 6 ill-Fig.1, and these are open on the inner or contact face of the WflllSPC- These feet are 1 tion. The cuter cavities are shown at 7 and 8, and lie in a plane nearer the wail or ceiling than the inner cavities. The inner cavities are sgmnrmirieeliy situated and are separated by the plate 9, from which there extends a. psrrition iii, which separates the cavities 7 and Under the ixwo outer edges of the piste 2'; he iiwts ere provided at 11 and 12, whereby eeinmunieetmn is had between the cavities :3 and 7 on one side and the cavities (5 end en the usher. In the preferred form of eteehm wherein cont-act is made with a sent-mi iPFI'fliiiill in the lamp, the pertitien 10 is pissed en ens side of the center, as is pieinly 7o simwn in Fi 1 and 4. The cavities Y and 8 new; he Eek. open 01' not, as desired and the Lire. iiiusireie the form given to .the see-ire?- es sent out from the factory and as pref ably molded in iorcelein or the like. Th ism wires whic supply current to the issue s i we at 13 and 14, and their insuisiiiin sf, i5 and 16. These insulated wires pass The inner face of the section 1,

bring the center of each wire 13 and 14 into t eef the contact-fess aspieiniy shown i. The wires are secured in this 0- liillewsz The insulation is out 0 of 8; ins wires i'er e distance eorrsspondin to the Wit'iil] ef the eavities 5 and 6, and the bare iii??? ere iirmi v :iiieehed by conducting means i1; iiis sealing-in strips. The wire 14 is S QiZLH'QI- i tie the shores-r leading-in strip 17 go by nave-es the s eserew 1S, and this strip 5, w i time it e 1 he pushed from the envity into vlie (as 1 Z, en as to lie fiat against 0 ei the plate 9,while extending i Siitfifi n in Fig. 1, where it 5 1n: the wire 14. A Screw. 19 gh as seprepriate opening in the d s. into the stri 17,80 as $0 lmld i'i; place. The leading-1n strip 20 is semrisi is ihs wire 33 in the same manneres 10o iiesi-riip ri shore for the strip i7; but the stri 2i? i Llzen the strip 1?,b0th stri s end (if the periitinn 16.

In order that all mistakes nmv be avoided in fitting one see tion upon the other, a projectioi'i, as 25, is on one of the sections and the other section is provided with the cavity 26 to receive the same when the two sections are rightly placed together. Scmicircular openings -7 are provided in the sides of the cavities and .24, res 'iccl'iively, and these openings reg ister with the similar openings heretofore mentioned for providing circular passages which accommodates the insulation 15 and 16 on the fitting wires. These semicircular openings should lit tightly down around the insulation on the wires, and. thus prevent access of moisture. The contact-lace ol' the section 22 is provided with smaller cavities 29 and 30, which lit over the heads of the screws 1.) and 21, respectively.

The outer side of the lamp-section 212 is provided with a cylindrical extension 31, containing the threaded metallic shell 32, the bottom of which shell is annular, as shown in Fig. 1, and surrounds an inward projection of the body oi the lamp-section 22, which is preferably fluted or grooved, us'shown in Figv 1. The metallic stem of the lamp is shown at 33 and screws into the shell 32, so as to bring the central terminal 34 down upon an appropriate terminal in the socket which, in the form shown, takes the shape of a spring 35, held in placr by the central screw 36 and having,' its end curled up over the head of said screw to make a sprint, contact with the lai'npterminal. The screw passes through rr-gistering openings in the two socket-sectim1s and screws into the leading-in strip 20 near its inner end. A retaining-weshcr 37 is preferably supplied, surrounding, the screw 36 and fitting it tightly enough to prevent the screw from dropping out when the lan'ip-scction is held in the position shown in Fig. l and before a lamp is inserted. This washer nniy be of any material, such as paper or other cheap stuff, and [its within an appropriate cavity in one or the other of the socket-sections. In the form illustrated the cavity is supplied on the lamp-section. The screw .38 passes through appropriate registering openings in the bottom of the shell and in the i we socketsections and screws into the threaded opcnin: in the strip 17 near the partition in.

When the whole device is :i.-senihl-.-.il with a lamp, as shown in Fig. 1. current c iterion, for lnstance, by the wire 13 passes through the strip 20 to the screw 36, thence bv the spring 35,to the lanni-terininal 334. Passing out by tlle terminal 33 and shelli2 the current traverses the screw 38,- the strip 17, and the wire 14' back to the generator.

, It will be seen that by the use of this form of socket the wall-sections can be rapidly adjusted in place and the feed-wires secured thereto before the lamp-supporting sections are adjusted in place. These latter are uickly secured by the two screws 36 and 38, which act both to hold the sections together and 2.

and to bring the current to the two terminals inside of the socket.

The parts made as described can be easily molded in porcelain or oth r npproprialiinn. lerial and require very little manipulation to prepare them lot the nmrliet. The exposed portions ol the wir s and of the hauling-in strips are so placed as to be entirely out ol' danger of contact with anything in the vicinity which might cause dii'liculty or danger by touching them.

Various changes can be made in this apparatus without departing from the spirit oi my invention, and l. am not to be limited to the precise detail. herein shown and described.

\Vhat .1 claim is I. in a device of the class described, a wallsection having; a pair of elct:trically-separatcd cavities on its inner side and a corresponding pair ol electrically-separated. cavities on its outer side and having openinqs joining each inner cavity to its correspom inc outer cav ity. two inctaiiic leading-in strips, one at each end, and each extending From an outer cavity through one of said openings into the corresponding inner cavities, means within each inner cavity for making: electrical coin inaction. between each eadingrin strip and n n electric wire. a iainp-snpporting section it'- ting over said vaii section, lamp-socket thereon, and mean ice making; eiectrical connections between each of said lending-in strips and said socket, suhstaiitially as de scribed.
